UNITED STATES CHRISTIE N. NEILSON, OF JACKSON, MICHIGAN.

LUBRICAIOR INDICATOR.

Application filed December 16, 1921.

To all whom it may concern:

Be it known that I, CHRISTIE N. NEILsoN, a citizen of the United States, residing at Jackson, county of Jackson, State of Michigan, have invented certain new and useful Improvements in Lubricator Indicators, of which the following is a specification.

This invention relates to improvements in lubricator indicators.

The main object of the invention is to provide a simple and efiicient electric lubricator indicator for automobiles.

Further objects, and objects pertaining to details and economies of construction and operation will definitely appear from the detailed description to follow.

I accomplish the objects of the invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this specification, in which:

Fig. I is a plan view of a transmission case of an automobile with a portion of the transmission cover door broken away to show details, the electric connection and indicator being shown diagrammatically.

Fig. II is an enlarged detail plan view of the main portions of iny improved indicator within the transmission gear casing of an automobile, portions of the gear casing being shown in section.

Fig. III is an enlarged detail sectional elevation taken on the line 33 of Figs. II, IV and V showing details of the float means and the electric contact devices.

Fig. IV is an enlarged detail sectional elevation taken on a line 44c of Figs. II and III showing details of the electric con tact terminals and the insulation therefor.

Fig. V is an enlarged detail sectional view taken on a line 55 of Figs. II and III showing details of the float rocker shaft means and the support therefor.

In the drawing the sectional views are taken. looking in the direction of the little arrowsat the ends of the section lines and similar numerals of reference refer to similar parts throughout the several views.

Considering the numbered parts of the drawing, 1 is the transmission casing of an automobile. 2 is the transmission casing cover door. 3 is the inner open top reser- Serial No. 522,823.

voir of my improved indicator means, the same being provided with small drain holes 3 in the bottom. This reservoir is secured to a supporting arm 4; by screws 5, 5, or otherwise, see Fig. II, andthe supporting arm 4 is clamped to the inside of the transmission case to hold the reservoir in a position somewhat elevated above the oil level, by the clamping bolt 6 extending between the opposite walls thereof. This bolt is provided with the clamping nut 7 which is locked in place by the lock nut 8.

A float arm 9 carries a float 10 adapted to float in the oil contained in the reservoir. This float is housed by the partial casing 10 slot-ted to accommodate the arm. The arm 9 is carried by the rockenshaft 11 which is supported in the U-shaped plate.12 having the upturned ends 13 within the side walls retained by spot welding or otherwise with in the reservoir.

A. sharp contact point 9 is on the upper side of the float arm 9. The opposite contact member 14 projects above the same so that the sharp point can penetrate its under surface when the oil fills into the reservoir to a suiiicientlevel. This contact member 14: is carried on the insulator block 15 which is secured to the inner side wall of the reservoir 3 by screws 16, see Fig. II. The contact member 14; extends through the enlarged aperture 17 and is consequently insulated by the insulating support 15. A conductor 18 is secured to the contact menu ber by the set screw 19 and extends out through a hole bored in one of the cover door cap screws 18 to a galvanometer or any suitable electric indicator 20 on the dash.

Current is sup-plied through a conductor 21 from the ammeter 22 which is usually disposed on the dash of the automobile. The electric current can, of course, be supplied from any source where it is generated about the automobile, but it is found that it can be conveniently connected by a very short connection to the circuit from the ammeter.

The operation of my improved indicator will be very clear from an examination of the details. The oil within the. transmission case, when there is a sufiicient supply, is agitated and splashed to thoroughly lubricate all adjacent parts. This splashing, when there is a sufficient quantity of oil present, tends to keep the reservoir 3 full and so long as there is sufficient lubricant April 28,1925. 1,535,435 C. A.
